CENTRlFUGAL MACHiNE.

SPECIFICATION forming part of Letters Patent No. 306,769, dated October 21, 1884.

I Application filed June 2i, 1884. No model.)

To (LZZ whom it may concern.-

Be it known that I, JOHN XV. PALMER, a citizen-of the United States of America, residing at Quincy, in the county of Adams and 5 State of Illinois, have invented certain new and useful Improvements in Centrifugal Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improvementin centrifugal machines ofthat class shown in the Patent No. 277,155, issued to R. B. Palmer May S, 1883; anditrelates to the peculiar combinations and the construction and arranger 5 ment of .parts hereinafter more particularly described, and then pointed out in the claims.

The accompanying drawing shows a verti cal central section of a machine constructed according to my improvement, in which A represents a hollow cast-shell forming a part of the frame, which is provided with supports or legs A, also hollow, which legs may be cast in one piece with the shell A, or made separatelytherefrom, as shown in the drawing, and

2 bolted or otherwise secured thereto. Around this shell a gutter, C, is formed, of graduallyincreasing depth, which is provided with a spout, c, at its lowest point. Mounted and secured by bolts and nutsaipon this gutter is a casing, D, within which is the basket E, having the inwardly-projecting flange e, and supported upon standards F, connected to the basket-carrier G, and arranged in such manner as to leave aseries of openings, f f f, between the 3 5 standards F, the bottom edge of the basket, and the basket-carrier. The basket-carrier G is of the shape shown in the drawing, and is provided with a cone, H, in which is cast or otherwise formed an oil-reservoir, h, and a sleeve, I, de-

pends from said cone and works in a bearing, J, connected with the shell A by the plate K, which may, however, if preferred, be a series of arms. Below the bearing J is a collar, i, bolted to the sleeve I to keep the basket from 4.5 rising. Passing through sleeve I is a shaft, L, carrying a band-pu1ley, M, and supported and revolving in a step, N, which is supported and held in ahub, O, of a spider, P, connected with the legs A. The step N is provided with a rack, n, in which mesh the teeth of a segment, Q, turning on a shaft, R, on which is keyed the lever S, which shaft is supported in suitable bearings in the spider P, and the whole is so arranged that by raising or depressing the lever S the segment will move the step up or down, as the case may be, and thus raise or lower the shaft.

Attached to the upper end of the shaft L is a dome, T, similar to the dome in the patent above referred to, and having a distributingplate, U, WlllCll also forms the bottom of the basket,whose outer edge terminates in a flange, a, that projects under shoulders f, that are formed on the upper parts of the standards F, which flange it thus forms a frictiondriver.

In the upper part of the shaft L is an oilchannel, Z, whose lower end terminates at the oil-reservoir h, and whose upper end is preferably provided with a screw, Z, to stop up said channel when the machine is in use. On removing the screw the reservoir h can be supplied With oil.

Then in operation, a very rapid motion is given to the distributing friction-plate U and dome T by means of a belt passing around the pulley M. The dome and friction-plate are raised by means of the lever S, segment Q. rack a, step N, and shaft L until the flange a presses tightly against the shoulders f or against the lower part of the basket E, thus making friction at this point, which causes the basket to revolve at-the same speed as the shaft.

The molasses or other material to be dried is fed into the center of the machine upon'the dome T,and by the centrifugal force generated by the rapid rotation of the dome it is thrown off again against the basket with great force, the granules of sugar adhering thereto, and the liquid portion, passing through it, 0 comes 'in' contact with it and runs down the inside of the casing D into the gutter C, where it escapes through the spout 0 into any suit able receiving-vessel. When the sugar or other material has revolved with the basket until it 9 5 has become dry, the lever S is reversed, lowering the bottom or plate U, and leaving the apertures f f f above said plate. The motion of the air caused by the revolving dome and friction-plate is now diverted from going through the small apertures in the inside of the basket, covered by the mass of sugar or solids adhering to or resting against it, and finds exit through the large apertures f f f beneath. The basket now stops, being relieved of its propelling-motor, (or it may be stopped more rapidly by means of a brake, not shown,) and the sugar or other material that has accumulated at the sides of the basket, having nothing to support itthe centrifugal force being diverted, and the material being also acted upon by the diverted current of air-falls down upon the continually-rcvolving plate U, where it is expelled by the centrifugal power there in action, through the aperturcsfff, into the hollow shell at A, where it falls through the hollow supports or legs A into any receivingreceptacle placed below. When the sugar is discharged, the plate is again raised by thelever S and its connections, the charge again run in, and the operation repeated.

From this description it will be seen that by my improvement at very convenient and effectual machine is made that will not only rapidly drive out the liquids from the solids, but will quickly and easily discharge the solids.

The friction driving device will be found to be very advantageous, and it has at least four distinct functions, viz: First, it drives the basket; second, it serves as a distributing-plate when the machine is in operation; third, it acts as a valve to close the discharge-a ien tures, and, fourth, it discharges the solids through said apertures when open.

It is evident that mymachine may be varied essentially in construction and arrangement without departing from the spirit of my i veution-for instance, in some cases I may make my machines without the hollow supports or legs A; or, instead of making the plate G and standards F separate, the plate G may be made with avertical flange to support the basket, and be provided with openings, through which the discharge may be made; or the basket E and standards F may be made in one piece. These and many other varia' tions may be made at the option of the constructer without essentially changing my invention.
